Application filed June 1, 1903. Serial No. 436,021.

To all whom it may concern:

Be it known that l, ELIZABETH M. Lauren, a citizen of the United States,residing at San Diego, in the county of San Diego and tate ofCalifornia, have invented new and useful Improvements in HeatingVessels, of which the following is specification.

My invention relates to improvements in that class or" heating vesselsas boilers or bath water heaters and more particularly to be used on gasor oil stoves.

The object of my invention is to provide a vessel with large heatingarea and that will utilize more of the heat, thus reducing the quantityof fuel usually necessary.

- In the drawings Figure l is a vertical sectional view of my invention.F 2 a top view of the same with the cover removed.

Similar characters of reference refer to similar parts throughout theviews.

The vessel may be annular or oblong. In this case I prefer to show anddescribe it as annular to he used on one fire of a gas or oil stove. Thevessel 1 is annular shape and is provided with a central tube 2extending from the base centrally to the top of the vessel. On theoutside or" the vessel 1 and extending around said vessel is an annularpassage or air space 3 which is formed by extending a hood down to flushwith the base or the vessel the lower edge being extended so as to causethe heat to enter the passage at 4. At the upper extremity of saidpassage are provided, a plurality of holes 5 for the exit of the heatwhich enters the passage at 4. 4

The vessel 1 is provided with an arched cover 6 which is provided with acentral opening 7 for the exit of the heat which enters the central tube2.

8 represents a pipe and 9 a valve which are used for the exit of thecontents of the vessel.

It can readily be seen that with this construction of heating vesselthat the heating surface is enlarged and that the passage 3 and tube 2,confine the heat close to the heating surface of the vessel the exitarea being a great deal smaller than the intake. This allows circulationand still confines the heat to the vessel heating surface.

Having thus described my invention what l claim as new and desire tosecure by Letters Patent is- In a water heater the combination of awater vessel ha *ing a central tube extending from top to bottom andconnecting with the lower outside surface for conveying the products ofcombustion through said vessel, an exterior hood or shield provided withperforations at the top for the exit of heat and extending to the planeof the bottom and there flanging outward and forming a heating pocketand passage around said vessel body and a cover for said vessel providerwith perforations for the exit of heat all substantially as set forth.

in testimony whereof I aiiix my signature in the presence of twowitnesses.
